![]() ![]() Other manufacturers offer systems similar to Griffin's and AAC's. For the rifles I have the flashhider on, I prefer the flashhider. If you asked me which kind of device I prefer, well, I'd say that for the riffles I have the brake on, I prefer the brake. Here is a picture of the AAC 51T flash-hider mount, and you will be able to see why the timing relative to the barrel is irrelevant: The suppressor is retained by a ratchet against the teeth on the flash-hider. And, it is a pretty effective flashhider too when the can is not mounted. ![]() It doesn't matter where the prongs are located relative to the direction of the bore when the flash-hider is mounted, because the 3 prongs are equidistant from one another and so the expelling of gases equidistant too, which means that it has no directional effect on the muzzle at the time the bullet exits.or more accurately perhaps, it acts on the muzzle in ALL directions simultaneously, so the effect is cancelled. My ACC 762-SDN-6 suppressor mounts to the rifle by means of a 51 tooth flash hider that has three prongs. Now, some flash-hider suppressor mounts are immune to timing, and it really doesn't matter where the gases are venting, so long as the device is properly torqued to the barrel. Here is a picture of the Griffin taper mount, and you will be able to see why the timing relative to the barrel is important: ![]() It's not hard to do, but it requires some patience. That may mean that you have to mount/dismount/remount the brake 2 or 3 times in order to get the timing right. So when mounting the device, the included shims have to added or removed accordingly so that once the device is tightened to spec, the ports are directing the gases horizontally, instead of off-kilter. if that makes sense.įor instance, the Griffin Armaments taper mount muzzle-brake that And圜 and I (and others) use for our Form 1 home built cans has two ports on either side that are designed to blow gas out horizontally at 90º to the direction of the bore. So that means that when you purchase one, it will sometimes come with a series of steel shim-washers that are used to correctly position the muzzle device as you tighten it up against the barrel shoulder. ![]() Some flash-hiders and all muzzle-brakes have to be timed to the aning that they are designed to expel the gases in specific directions - directly upwards, or off at 90º relative to the bore, for instance. Mind you, I'm not debating, just seeking greater information. Seemed pretty simple and no specialty tools required. I've watched a few utube videos with the flash hider being removed off an AR with a 3/4" wrench with the rifle barrel firmly but carefully situated in a vise. ![]()
